GAS-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 268,368, dated November 28, 1882.

Application filed October 12, 1882. (No model.)

To all whom 'it may concern:

Be it known that I, GRIFFIN S. LAGEY, a citizen of the United States, residing in the city of New York, in the county and State of ANew York, have invented certain new and useful Improvements in Gras-Regulators; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had tothe accompanying drawing, which forms a part of this specification.

This invention is specially designed as an improvement upon that described in Letters Patent No. 255,517, granted March 28, 1882, to me for a gas-regulator, and has for its object to increase the efficiency and durability and improve the general operation thereof.v ln the regulator described in my said patent the air which is above the diaphragm is continually changing, it being received and discharged through a minute hole placed in the cover as the diaphragm is lowered or raised consequent upon the variation of pressure below it. The result is that the air which is discharged from above the diaphragm emits a disagreeable odor into the apartment, contracted from the contact of the air with gas-contaminated surfaces, the lubricant, and other extraneous matter. Another disadvantage attending the continual change of the4 body of air above the diaphragm is the deterioration of the leather or other substance of which it is composed, which is found not to result where the body of air is constant or unchanged. To obviate the said defects involved in the use of my invention patented as aforesaid is the purpose of my present invention.

To these ends it consists in a device applied to my patented regulator whereby the air above the diaphragm and in immediate contact therewith may have the requisite motion resulting from the rise or fall of the diaphragm and still be isolated or separated from the outer air or that in communication with the apartment. The construction employed prevents the escape of unpleasant odor from the regulator, as the air in contact with the gas-contaminated surfaces and other air-tainting agencies within the regulator is water-sealed against the air in direct communication with the room. It is also seen that the same appliranged substantially after the manner of a gas- 6o ometer used by gas-works. The outer easing ot' the air-chamber A (marked a) is secured to the cover of the regulator in any suitable manner. Within the casing a, is a wall, a', extending part of its height, between which wall and the casing itself is formed a liquid space, b. The solid bottom of the casing is pierced by an aperture, c, which leads to the space between the cover and the top surface of the diaphragm. The lid of the easing c is represented 7o by d, and is pierced with a small aperture, e. An inverted cup is shown byf, which cup extends into the liquid in the space b, the interior of the cup being by reason of the aperture c in free communication with the space be'- 75 tween the cover of the regulator and the upper surface of the diaphragm. It will be seen that the air above the diaphragm is free to move as shown by the arrows a: x, the cup j' rising and falling with the movement of the 8o y diaphragm, and that the air in contact therewith is a constant body, or not subject to change, it being isolated from the outer air by the Water seal. It is also apparent that the air discharged into the apartment from the regulator is not polluted by contact with foreign or odorous matter, as in my patented invention; and, further, that'the diaphragm, not being subjected to a changing body ot air, is

not liable to the deterioration or injury above 9o referred to.

The shape of the air-chamber A is unimportant. It may be made annular, so as to surround the cover, or in box or other form, it

being onlynecessary that it shall fultill the conditions above described.

I claim as my inventioni 1. An air-tight dry gas-regulator having a flexible diaphragm, the chamber above which is in communication with a space sealed from roo the outer air, subslantiallyas deserlbed,where 3. In a diaphragm gas-regulator, a casing by the diaphragm may have free movement having a liquid-space, combined with a perfoand esoapeof gaseous or unpleasant odors from rated lid and an inverted onp, substantially as i5 the regulator to the apartment be prevented, and for the' purpose set forth.
